It’s been quite awhile since we’ve seen you and {your dog Lucky}. I get worried when I don’t hear from a valued {pateint/client} like you.

Did we do something to offend you? Or were you dissatisfied with your last visit for some reason? I want you to realize we’re here for you and we sincerely care about you and {the health of your pet}. So, if something is wrong, please let us know and I’ll make it better.

You know, I’d really like to see you again.

And that’s why I’m writing to you. I’d like to make a special one-time offer, I’m going to buy you a free {flea consultation or screening or nominal service}. So now you have a good reason to come back again.

You see, with {flea and tick season right around the corner, allergy season, etc.} I couldn't think of a better way to help you and {your pet prepare}. There is absolutely no charge and no obligation to get anything else - I just want to make sure you are doing well.
